Oikos is an experimental project formed in 2007 by Rafael Femiano and David San Martín. Initially conceived as a guitar improv experiment, the duo quickly evolved towards their cinematic signature sound and released their first record Ecotono on Utech Records in 2011. In 2012, San Martín moved to Moscow and Femiano continued Oikos as a solo act. Following Vigilia (2013), Femiano presents his second, solo Oikos LP, The Great Upheaval, co-released by Envelope Collective and Knockturne Records. The Great Upheaval is an imaginary soundtrack for every moment in history ravaged by violence and superstition. It is a collection of pieces projecting landscapes dusted by seizures and turmoils. Layered compositions are packed with electricity and analog walls, acoustic textures, drone strings and cinematic looped-movements. A sonic cathedral illuminated only by the fire that remains after battle and precedes the cult - a sonic miasma for each end of cycle.
